TECHNICAL FIELD

The present application relates generally to connectivity in the contextof distributed or cellular communications.

BACKGROUND

Distributed, or peer-to-peer, and cellular communications can take placein the contexts of person-to-person, person-to-machine,machine-to-person, or machine-to-machine communication.

Person-to-person communication comprises inter-person telephonecommunications, for example. Cellular networks originally designed tosupport person-to-person communications have been used also formachine-centric communication. This may entail a person accessing anetwork such as the Internet using a personal communications device, ora home security appliance reporting data to a central repository using acellular network as communication medium, for example. In general,machine-centric communications may be any communication where at leastone endpoint is not a person but a machine. In detail, machine-centriccommunication comprises communication between two automated machines.

The Third Generation Partnership Project, 3GPP, has studied requirementsrelating to machine-centric communications. Machine-centriccommunications have characteristics that differ from person-centriccommunications, for example where both endpoints are static, automatedmachines mobility procedures may be rarely needed. In some cases, thetype of machine affects the types of communication required, for examplea closed-circuit camera feed may only require a constant quality ofservice selected as suitable but not excessive for conveying a videofeed from the unit. In such a case, procedures for dynamically changingthe quality of service may be rarely, if ever, needed.

DETAILED DESCRIPTION OF THE DRAWINGS

An example embodiment of the present invention and its potentialadvantages are understood by referring to FIGS. 1 through 4 of thedrawings.

FIG. 1 illustrates an arrangement where some embodiments of theinvention may be practiced. FIG. 1 illustrates apparatus 110, which maybe for example a cellular telephone or an automated machine. Examples ofautomated machines include closed-circuit television monitoring machinesand automated meters such as electricity or gas meters. Apparatus 110may be configured to autonomously, without user intervention, transmitinformation stored in an internal or external memory of apparatus 110.Apparatus 110 may be configured to, responsive to determining thatinformation stored in a memory of apparatus 110 needs to be transmitted,cause a connection 115 to be established. Apparatus 110 may beconfigured to transmit information periodically, responsive to adetermination that a predetermined amount of information has accumulatedin a memory of apparatus 110 or responsive to a trigger event. Examplesof trigger events include detection of motion in a motion sensor,detection of a predetermined temperature in a temperature sensor,determination that a temperature has changed by a predetermined numberof degrees in a predetermined amount of time, or a determination that ausage rate of electricity or gas changes. In some embodiments, a triggerevent is reception in apparatus 110 of a request to provide data.

Connection 115 allows apparatus 110 to transmit information to basestation 120. Connection 115 may also allow apparatus 110 to receiveinformation from base station 120. Connection 115 may be a connectionaccording to wideband code division multiple access, WCDMA, globalsystem for mobile communications, GSM, long term evolution, LTE, orother wireless technology. In some embodiments connection 115 may be awire-line connection instead of a wireless connection. Connection 115may comprise an uplink connection for conveying information fromapparatus 110 to base station 120. Connection 115 may comprise adownlink for conveying information from base station 120 to apparatus110. Base station 120 comprises equipment configured to supportconnection 115, for example in embodiments where connection 115 is inaccordance with WCDMA technology, base station 120 comprises at leastequipment arranged to support WCDMA connections.

Connection 115 may comprise resources reserved for the connection. Radioresources of a wireless connection 115 may comprise frequency, time,code or space resources, for example. Resources reserved for connection115 may comprise a certain time-slice on a certain spreading code, whichis used to spread a signal over a certain frequency band. In embodimentswhere connection 115 is wire-line, resources of the connection maycomprise timeslots allocated to connection 115. Connection 115 maycomprise encryption, authentication and charging aspects handled by thesystem in which base station 120 is comprised. An active connection 115may comprise data transmission, or at least periodic keep-alive packetsarranged to prevent timeout timers from dismantling connection 115.Transmitting, receiving and processing keep-alive packets consume acertain amount of energy in apparatus 110 and base station 120,wherefore connection 115, when active, consumes energy even when noactive data transmission is ongoing.

Backbone connection 125 conveys information between base station 120 andcore network 130. Core network 130 may be connected to more than oneradio-access network, each radio-access network comprising a pluralityof base stations. Core network 130 may be shared between networkoperators. Backbone connection 125 may be wire-line or wireless, anexample a wireless backbone connection 125 is a microwave linkinterconnecting base station 120 and core network 130. Core network 130may comprise a gateway node, not illustrated, operatively connected toexternal networks. In an example embodiment, apparatus 110 may beconfigured to transmit information via base station 120 and core network130 to a proprietary network or a corporation that owns apparatus 110.An example of such an arrangement is one where apparatus 110 is anelectric meter configured to transmit information to corporate networkof an electric utility corporation.

In cases where apparatus 110 transmits information infrequently, it maybe advantageous to release connection 115 when no transmission isongoing in order to release the resources allocated to connection 115for active communications by other apparatuses, or alternatively oradditionally to conserve energy spent in keeping connection 115 active.Whether it is advantageous to release connection 115 in-betweentransmissions may depend on, for example, the ratio of transmission gapsto lengths of transmissions wherein a transmission gap is a length oftime from the end of a transmission to the start of a next transmission.

When connection 115 is to be released after a transmission, apparatus110 may transmit to base station 120, over connection 115, a connectionteardown signal. Responsive to receiving a connection teardown signal,base station 120 may be configured to autonomously or in co-operationwith core network 130 cause connection 115 to be released and resourcesallocated to connection 115 to be considered available for otherconnections. Alternatively apparatus 110 may, responsive to havingcompleted a transmission of information, simply wait. Responsive todetermining that connection 115 has been inactive for a predeterminedperiod of time, base station 120 and/or core network 130 may initiatereleasing connection 115. The predetermined period may be called atimeout period, which may be monitored by base station 120 and/or corenetwork 130. Connection 115 may be considered to be inactive if there isno traffic in either the uplink or the downlink direction during thetimeout period, aside from keepalive packets. Transmitting the teardownsignal accomplishes release of connection 115 faster than the timeoutperiod, however transmitting the teardown signal consumes energy anddepending on the technology utilized in connection 115, may causeinterference to other connections sharing at least partly the resourcesallocated to connection 115.

In accordance with certain embodiments of the present invention, whenapparatus 110 determines that information stored in a memory ofapparatus 110 needs to be transmitted, apparatus 110 requests aconnection 115 to be established between apparatus 110 and base station120 with an indication relating to releasing resources allocated toconnection 115. The indication may be transmitted in an initial requestfor connection 115, or as part of a signaling exchange between apparatus110 and base station 120 to establish connection 115. For example, theindication may be comprised in a radio resource control connectionrequest message, or a radio resource control connection setup completemessage sent from apparatus 110 to base station 120. In general,signaling between apparatus 110 and base station 120 aimed atestablishing connection 115 comprises new connection establishmentmessages of various types.

In some embodiments, the indication indicates a type of connection 115,for example that connection 115 is not conversational, or thatconnection 115 is a “one-off” connection comprising primarily a block ofinformation transmitted from apparatus 110. The indication may alsoindicate an establishment cause conveying the purpose of connection 115,which can be taken into account when determining when to releaseconnection 115 without an explicit teardown signal from apparatus 110.An establishment cause can differentiate a machine-centric connection115 from person-to-person connections that base station 120 and corenetwork 130 may also serve. The operator or operators of base station120 and core network 130 may also be interested to compile statistics onhow much machine-centric communication their network carries. Anindication as to connection type can facilitate compilation of suchstatistics.

In some embodiments, the indication comprises at least one quantityrelating to connection 115. For example, an indicated quantity may be anamount of data to be transmitted over connection 115. In embodimentswhere apparatus 110 requests connection 115 responsive to accumulating acertain amount of data, apparatus 110 will be in possession of thequantity of data to be transmitted over connection 115 prior toconnection 115 being established. Responsive to receiving an indicationof data quantity, base station 120 and/or core network 130 may beconfigured to cause connection 115 to be torn down responsive toreceiving the indicated quantity of data without waiting for a timeoutand/or without waiting for a teardown signal from apparatus 110.Apparatus 110 may be in possession of knowledge relating to the quantityof data to be transmitted over connection 115 also by other ways, forexample apparatus 110 may be configured to stream or send a known amountof data at set intervals or responsive to a trigger. An example of thiswould be an embodiment where apparatus 110 is a surveillance cameraconfigured to transmit one frame of image data responsive to amotion-sensor detecting movement or at set time intervals.

In some embodiments, the quantity relating to connection 115 is adesired timeout period for connection 115. When apparatus 110 knows thatconnection 115 is established to transmit a block of information to basestation 120, apparatus 110 will also know that subsequent to thetransmission of the block of information, connection 115 will beredundant. The timeout period may be set to a default setting in thecellular network where base station 120 is comprised, and the defaultmay be selected for interactive communications, for example. Ininteractive communications, an appropriate timeout period may be longcompared to an appropriate timeout period in machine-to-machinecommunications. When a user is browsing the Internet, for example, usinga mobile device, he will occasionally click on links to request furtherweb pages to be downloaded into his device. The time in-between clicksmay be in the order of minutes and it would ne inappropriate to teardown the connection between his mobile device and the network duringthat time. In contrast, subsequent to the block of information beingsuccessfully sent connection 115 may be torn down more or lessimmediately. Therefore apparatus 110 may insert in a connectionestablishment message a requested timeout period, for example oneselected from one of the following ranges, for example: one to tenseconds, 160 to 320 milliseconds, 320 to 640 milliseconds and 640 to1280 milliseconds.

Responsive to receiving an indication relating to release of resourcesallocated to connection 115, the network base station 120 is comprisedin may take appropriate actions, for example applying a requestedtimeout value, or allocating a limited amount of resources to aconnection indicated as being meant to convey only a relatively smallamount of information. The network may also choose to allocate resourcesin a lower-capacity technology to a one-off or low-data connection. Forexample, the network may choose to attach apparatus 110 to base station120 using GSM technology instead of WCDMA or LTE technology. The networkmay also compile statistics on one-off connections, or overall onconnections providing an indication relating to release of resources ina connection establishment message.

In some embodiments, responsive to receiving an indication that aconnection is one-off, a network node such as, for example, base station120 or a node in the core network 130 may be configured to apply ashorter timeout period to the connection. In other embodiments, anetwork node such as, for example, base station 120 or a node in thecore network 130 may be configured to apply a shorter timeout period tothe connection responsive to receiving any indication relating torelease of resources allocated to the connection.

FIG. 2 illustrates an example apparatus 201 capable of supportingembodiments of the present invention. The apparatus may correspond toapparatus 110, base station 120 or a node in core network 130 of FIG. 1,for example.

FIG. 3 is a flowchart of an example process according to someembodiments of the invention. In phase 310 a new connectionestablishment message is received by a base station or an access point.The new connection establishment message comprises an indicationrelating to releasing resources allocated to the new connection, asdescribed above in connection with FIG. 1. In phase 320, the basestation or access point participates in establishing the new connectionthat the new connection establishment message relates to. Phase 320 maycommence before, during or after phase 310. In phase 320, the basestation may take the indication into account when allocating resourcesto the new connection, for example the base station may decide to keepone-off type connections in a certain radio-access technology or assignresources to connections established with the indicator from a block ofradio resources reserved for connections of the type. Another example ofa way in which the base station, or other network node, may take theindication into account when allocating resources is that only a setbandwidth is allocated to the new connection and algorithms used inother traffic to increase a bandwidth of a data connection in use aren'tused to modify the bandwidth of the new connection while it is in use. Ayet further example is that a quality of service that is lower than anormal, or default, quality of service allocated to a new connection isallocated to the new connection established with the indicator. In phase330, the new connection is released in accordance with the receivedindication.

As discussed in connection with FIG. 1, the indication may specify thatthe new connection is a one-off connection, the indication may specify arequested timeout period, or the indication may specify an amount ofinformation to be conveyed over the new connection, for example.Releasing the new connection in accordance with the indication maycomprise modifying the behaviour of the base station or access pointresponsive to the indication. In detail, where the indication specifiesthat the new connection is a one-off connection, the base station oraccess point, or other network node, may be configured to cause the newconnection the be released substantially responsive to determining thenew connection has been dormant for a timeout period that is shorterthan a default timeout period. In embodiments where the indicationspecifies an amount of information to be conveyed over the newconnection, the base station or access point, or other network node, maybe configured to cause the new connection the be released substantiallyresponsive to determining that the specified amount of information hasbeen received over the new connection. In embodiments where theindication specifies a requested timeout period for the new connection,the base station or access point, or other network node, may beconfigured to cause the new connection the be released substantiallyresponsive to determining that the new connection has been dormant forthe requested timeout period.

The amount of data storedin phase 410 may depend on the embodiment. In embodiments where theapparatus is to transmit data only once per month, for example, theapparatus may be furnished with memory capable of storing dataaccumulated over a month. In embodiments where the apparatus isconfigured to transmit data responsive to a trigger event, memoryrequirements may be less strict, for example if the apparatus isconfigured to only begin collecting data responsive to the triggerevent. In some embodiments, the apparatus is configured to accumulatedata for periodic, for example monthly or weekly, transmission but isstill configured to transmit accumulated data responsive to a triggerevent.

In phase 420, the apparatus makes a determination that a new connectionis required to be established. This determination may comprise, forexample, a trigger event or a determination that a condition defined inthe apparatus is fulfilled. For example, a condition may comprise thatthe present day is a certain day of a month, for example the firstcalendar day of a month, or that a certain number of hours, days, weeks,or other time units has elapsed from a previous transmission. Acondition may also comprise that a certain proportion, for example apercentage, of a memory of the apparatus is filled with accumulateddata. Other kinds of possible trigger events are described above. Phase420 may occur before, after or during phase 410.

In phase 430, the apparatus may be configured to transmit a newconnection establishment message, for example a radio resource controlconnection request or connection setup complete message. The newconnection establishment message comprises an indication relating toreleasing resources allocated to the connection. As discussed above inconnection with FIG. 1, the indication may comprise an indicationrelating to a type of the new connection or the indication may comprisean indication of a quantity relating to the new connection, for example.
